openvpn recusando conexões com freeradius

Question

Eu instalei o openvpn e o freeradius do yum e instalei o radiusplugin_v2.1a_beta1.tar.gz, mas estou tendo problemas de conexão com o erro:

XML-RPC: ConnectionRefusedError: 10061: No connection could be made because the target machine actively refused it..

Eu adicionei o seguinte ao banco de dados (mysql)

mysql> INSERT INTO radcheck VALUES (1,'jpeterson','Password','==','netopia1');
mysql> INSERT INTO radreply VALUES (1,'jpeterson','Trapeze-VLAN-Name',':=','corp');
mysql> INSERT INTO radreply VALUES (2,'jpeterson','Session-Timeout',':=','300');

tentando usar o usuário jpeterson e a senha netopia1

Eu tenho olhado em / var / log / messages e /var/log/radius/radius.log, mas não vejo muito.

EDIT: Eu tive openvpn trabalhando ao usar o PAM.

EDITAR:

Agora, quando eu uso meu telefone ou a antiga conexão vpn hat tem o arquivo server.crt eu recebo isso no console:

[root@vpn ~]# Mon Jan  7 23:03:54 2013 RADIUS-PLUGIN: Got no response from radius server.
Mon Jan  7 23:03:54 2013 Error: RADIUS-PLUGIN: BACKGROUND  AUTH: Auth failed!.


[root@vpn ~]# Mon Jan  7 23:05:23 2013 RADIUS-PLUGIN: Got no response from radius server.
Mon Jan  7 23:05:23 2013 Error: RADIUS-PLUGIN: BACKGROUND  AUTH: Auth failed!.

Depois de algumas pesquisas, descobri isso, mas não sei o que significa:

"Got no response from radius server" means that the plugin does not receive any packet from the RADIUS server.

Can you check that your RADIUS server responses to an ACCESS-REQUEST RADIUS packet with an ACCESS_REJECT packet, which includes a response message? Does the server response in the interval which is configured in the plugin configuration file?

E eu também preciso ter um arquivo cert para logar mesmo se eu usar o FreeRadius?

    

Answer 1

Eu acho que é necessário ter autoridade de certificação, mas não é necessário ter chave privada com o arquivo .key e .crt ao usar o diretório ativo s, como LDAP e outras ferramentas de autorização, como radius
